Your mod when installed alongside Metalchests and Electroblob's Wizardry causes a dedicated server to kick a player when they try to pick up a metal chests upgrade. The exception appears to be thrown by ebwizardry, but on the 3rd line of the trace cuisine is mentioned. Removing cuisine stops the exception from being thrown and prevents the player from being needlessly kicked.
